The basic working principle of the drilling anti-lifting control device of the embodiment is as follows:

When the ram blowout preventer is opened again after being closed, a pressure sensor 11 arranged on a tee joint 3 communicated with a liquid opening pressure loop acquires a liquid opening pressure value and transmits the liquid opening pressure value to an AD conversion module, a controller monitors the liquid opening pressure value in real time and transmits the liquid opening pressure value to an integrated industrial personal computer 8, on one hand, the integrated industrial personal computer 8 displays the liquid opening pressure value to an operator, and if the liquid opening pressure value is lower than a minimum opening hydraulic value, the controller enables an audible and visual alarm 9 to send an audible and visual alarm signal; on the other hand, according to the set opening pressure value, the integrated industrial personal computer 8 sends an instruction to enable the two-position three-way normally closed solenoid valve 5 to recover to a normally closed state, and the locked winch is unlocked and the audible and visual alarm 9 is closed.

It is well known for a driller to effect closing or opening of ram blowout preventers by operating a handle on the operator's station. The handle is located in three gears which are respectively a closed position, a middle position and an open position. When the handle is placed in a closed gear, the locking hydraulic circuit of the ram blowout preventer is pressurized, and the opening hydraulic circuit of the ram blowout preventer is not pressurized. When the handle is placed in an open gear, the opening hydraulic circuit of the ram blowout preventer is pressurized, and the locking hydraulic circuit of the ram blowout preventer is unpressurized. When the handle is placed in the neutral position, neither the locking hydraulic circuit nor the opening hydraulic circuit of the ram blowout preventer is pressurized. In actual operation, the ram blowout preventer is closed, and then the handle is put in the middle position. At this time, the ram blowout preventer is locked, but the locking hydraulic circuit of the ram blowout preventer is not hydraulic. If the winch is started or not is judged only by the existence of hydraulic pressure in a locking hydraulic circuit of the ram blowout preventer, misoperation can occur to cause the drilling tool to be lifted off. Therefore, while monitoring the locking hydraulic pressure of the ram blowout preventer, it is also necessary to monitor the opening hydraulic pressure of the ram blowout preventer, and only when the opening hydraulic circuit of the ram blowout preventer has pressure, the winch is allowed to be started.
